Mount Kanmuri

Mount Kanmuri is a lava dome that rises about 1,409 meters (4,625 feet) within the Hakone volcanic complex in central Japan. Its slopes display volcanic features and rock formations typical of the calderas geological history and structure.

The mountain formed roughly 2,900 years ago from phreatic eruptions on Mount Kami's northwestern side, creating its present dome shape. This volcanic event was part of the ongoing geological changes that built the Hakone region.

The mountain's name comes from its shape, which resembles the traditional Kanmuri crown worn by Japanese court nobles during ceremonies. This visual link remains visible today in the dome's curved outline when viewed from different angles.

Three main hiking trails provide access to the summit, each starting from different stations and offering varying difficulty levels. Visitors should prepare for changing conditions depending on the season and wear sturdy footwear.

The mountain's formation altered local geography by damming the Haya River, which led to the creation of the Sengokuhara plain and Lake Ashi. This side effect of volcanic activity reshaped the entire landscape of the Hakone region.
